Both theAirEngine 5761-21andAirEngine 6761-21Tare part of Huawei's Wi-Fi 6 access point lineup and are equipped with2.5GE uplink ports. These ports provide higher bandwidth capabilities compared to standard Gigabit Ethernet (GE) ports, making them suitable for environments with high data throughputrequirements.The inclusion of 2.5GE uplink ports ensures that these APs can handle modern applications like HD video streaming, IoT devices, and cloud-based services without bottlenecks.

Fault Management in Autonomous Driving Networks:

Huawei's autonomous driving network leverages AI and machine learning to achieve rapid fault detection, analysis, and resolution.

Fault Management Metrics:

Locate faults within 1 minute:AI-driven tools quickly identify the root cause of issues.

Analyze faults within 3 minutes:Advanced analytics provide detailed insights into the nature and impact of faults.

Rectify faults within 5 minutes:Automated remediation workflows resolve issues promptly, minimizing downtime.

Conclusion:The statement is TRUE because Huawei's autonomous driving network meets these fault management metrics.

TheS6730-H24X6Cmodel in the CloudEngine S6730 series supportsMACsec (Media Access Control Security), providing Layer 2 encryption for secure data transmission. MACsec ensures confidentiality, integrity, and replay protection for Ethernet traffic, making it ideal for sensitive environments like financial institutions and government networks.Other models in the series, such as the S6730-S24X6Q, do not support MACsec, limiting their use in scenarios requiring advanced security features.

MACsec (Media Access Control Security) is a Layer 2 encryption protocol that ensures secure communication between devices in a network. It provides data confidentiality, integrity, and replay protection at the Ethernet layer.

The following models in the Huawei CloudEngine S6730 series support MACsec:

S6730-H48X6C : This switch supports MACsec on its high-speed ports, ensuring secure communication for critical applications.

S6730-H24X6C : Similar to the H48X6C, this model also supports MACsec, making it suitable for environments requiring robust security.

S6730-H24X4Y4C : This model also includes MACsec support, providing advanced security features for enterprise networks.

However, the S6730-S24X6Q does not support MACsec. It is designed for scenarios where Layer 2 encryption is not a primary requirement.

Thus, the correct answers are A , B , and D .

Challenges in Campus Networks During the All-Cloud Era:

As enterprises transition to cloud-based architectures, campus networks face several challenges due to increased complexity, scalability demands, and integration with cloud services.

Explanation of Each Challenge:

Difficult network scaling:As businesses grow, scaling traditional campus networks to meet increasing demands becomes challenging without proper automation and flexibility.

Cloud outpacing network:The rapid adoption of cloud services often surpasses the ability of traditional networks to adapt, leading to performance bottlenecks.

Wi-Fi discontinuous networking:Ensuring seamless Wi-Fi coverage and connectivity across large campuses is a significant challenge, especially in environments with high user density.

Slow fault locating:Traditional networks lack advanced tools for real-time monitoring and troubleshooting, resulting in delays in identifying and resolving issues.

Cross-domain fragile infrastructure:Managing multiple domains (e.g., wired, wireless, and cloud) introduces complexity and increases the risk of failures if not properly integrated.

Conclusion:All the listed challenges are valid and commonly faced by enterprises moving toward the all-cloud era.

As enterprises transition to cloud-centric architectures, campus networks face several challenges:

Slow fault locating:Traditional networks lack intelligent tools for rapid fault detection and resolution, leading to prolonged downtime.

Wi-Fi discontinuous networking:Poorly designed wireless networks result in coverage gaps and inconsistent user experiences.

Cloud outpacing network:Cloud services evolve faster than traditional networks can adapt, creating bottlenecks.

Difficult network scaling:Legacy networks struggle to scale dynamically to meet growing demands.

Cross-domain fragile infrastructure:Fragmented management across domains (e.g., wired, wireless, WAN) leads to inefficiencies and vulnerabilities.

Addressing these challenges requires modern solutions like SDN (Software-Defined Networking), AI-driven O&M, and unified management platforms.
